As you may know from a previous post I believe recycling paper and metals to be a complete waste of time and actually harmfull.
I am just watching a documentary extolling the virtues of recycled water. So I have done a bit of research
My first stop was wikipeadia
http://en.wikipedia.org/wiki/NEWater
They recycle water in both singapore and london seemingly. I have been looking for stuff online about recycled water in london and can’t see anything. I don’t think the “recycled water” in London is quite the same as the “recycled water” they are reccomedning elsewhe. After a great deal of digging I have found the answer yes london and theier water “recycling ” is totally different to what is now being proposed
